Sorry I cannot make STC due to lack of knowledge of QT.
In stead, I explain what gnuplot do.

On gnuplot for qt, 
plot is done by child process named gnuplot_qt. 

When gnuplot connect with gnuplot with 
  qt->socket.connectToServer(server);


without the above patch ()
qt_safe_socket(PF_UNIX, SOCK_STREAM, 0, O_NONBLOCK)))
gnuplot cannot connect with gnuplot_qt.

with the above patch ()
qt_safe_socket(PF_UNIX, SOCK_STREAM, 0))
gnuplot can connect with gnuplot_qt.

Perhaps qt with O_NONBLOCK is some wrong with process connection.
